Safe mode

Safe mode
If the ADDR_L voltage > 3.00V (ADDR_L pin shorted to ADDR_H) is detected when
the module starts (during power up) the application will not be loaded. This is a special
start-up mode that is used for master modules and puts the unit in a safe state without
starting any application.
When ’safe mode’ is desired, a jumper is put across pins 1 and 14 on the MC2 and 7
and 8 on the MC3/MC31, in place of an ID-Tag. The MC3/MC31 will also start in safe
mode if the ID-Tag is absent.
